ELLIS R. DUMBOLTON, OF LONG ISLAND CITY, NEW YORK.

BOUNGING CANE.

Application filed March 1, 1924. Serial No. 696,256.

To all 10. 2 am it may concern:

Be it known that I, ELLIS R. DUMBOLTON, a citizen of the United States, residing at Creek Avenue and Fourth Street, Long Island City, New York, have invented certain new and useful Improvements in Bouncing Canes, of which the following is a specification.

My invention relates to bouncing canes and more particularly to a bouncing cane which may be used as an amusement device.

One of the objects of the invention is to provide a bouncing cane which will smartly rebound when dropped, which will return to the hand after bouncing, and which can be cheaply manufactured.

With the above and other objects in view my invention consists in the parts, improvements and combinations more fully pointed out hereinafter.

Referring to the drawings:

Figure 1 is a front elevation of my bouncing cane on a reduced scale.

Figure 2 is adetail view of the end of the cane, partly in section, and provided with a resilient wire tip.

Figure 3 is a detail view of the end of the cane and tip taken at right angles to figure 2.

Figure t is a transverse section on line 4& of Figure 2 showing the tip.

Figure 5 is a perspective view of the tip.

In the drawings, the staff 1 of the cane, which may be of wood or metal, is surmounted by a knob 2. The ground end of the cane receives a resilient wire tip. The end of the cane is perforated and the ends 3 of the wire tip are inserted in the perfora tion. A metal cap 4 may be used to prevent splitting of the end of the stick. The tip which i have found gives the most highly resilient eflect comprises a wire frame in which the wire is bent so as to provide a series of loops surmounted by an arched top. In the best embodiment of the inven tion two curved or looped portions are provided, arranged at right angles to each other. Each port-ion includes a pair of loops. The end portion is provided with two end loops 5, 6 arranged in one plane and the middle portion comprises a pair of loops 7, 8 arranged in a plane at right angles to the end portion, the middle portion terminating in a flexible arched top or vertex 9 which unites the two middle loops. The top 9 strikes the ground or surface against which the cane is dropped or impelled. The wire used for the tip may be spring steel wire such as steel piano wire. The four loops and the arched top coact to give great resiliency to the top. I have also found that by reason of the right angled relation between the end looped portions and the middle looped portions, all parts of the tip frame, beyond the staff, contribute to the springiness of the tip, the looped .por tions of each part making the part sprlngy and the parts at right angles adding their springy effect. The middle looped portions are extended so as to form an arch with its top lying in the axial projection of the. staff of the cane. This also contributes its springy effect. One continuous spring from one end of the tip wire to the other end is thus produced.

Having thus described the invention, its operation will be clear and it will be understood that changes may be made in the construction of the tip without departing from the principle of the invention.

lVhat I claim and desire to secure by Letters Patent is:

1. A bouncing cane provided with a resilient wire tip, the tip provided with looped portions adjacent to its ends, and having middle looped portions adjacent to the former, the middle looped portions being united to form an arch whose top lies in the axial projection of the staff of the cane.

2. A bouncing cane provided with a resilient wire tip, the tip provided with looped portions adjacent to its ends, said end looped portions being in one plane, and having middle looped portions adjacent to the former, the middle looped portions being united to form an arch whose top lies in the axial projection of the staff of the cane.

3. A bouncing cane provided with a rc silient wire tip, the tip provided with looped portions adjacent to its ends, said end looped portions being in one plane, and having middle looped portions adjacent to the former, said middle looped portions lying in a plane at right angles to the plane of the end looped portions, the middle looped portions being united to form an arch whose top lies in the axial projection of the staff of the cane.

l A bouncing cane provided with a resilient wire tip, the tip provided with two loops, one loop adjacent toeach end, both loops lying inone plane, said tip also hav ing middle looped portions having two loogs.

5. A bouncing cane provided with a resilient Wii'e tip, the lip provided with two loops one loop adjacent to each end, both loops lying in one plane, said lip also lnwing middle looped port-ions having; info loops, the middle loops being adjacent to the end loops, an zip-en with which the middle loops are united.

6. A bouncing cane provided with a Wire resilien' tip, said tip having two ends, end loop poi-don in one plane adjacent to the nds, followed by middle loop portions in one plane at substantially right angles to the plane of the end loop pontions, said middle loop portions being extended so as to form an arch with ifs top lying in the axial projection of The stall of the cane.

A booming cane provided with :1 sotip the tip comprising :1 spring i el wire imine formed into plurality of loops, the said frame having an arched. aoex wlxielw. sniinonnts the loooed portions of the fimne.

in testimony whereof I have signed my n ne to this specification.

ELIAS nTOli.
